因此，为保证核废料地下处置的安全性，研究盐岩在一定温度条件下的物理力学特性十分重要。

So the study of the physical and mechanical properties of heated salt rock is important and essential to ensure the safety of nuclear wastes disposed in salt rock.

高温岩体地热开发及核废料的地下处置等需要对高温高压下花岗岩体的力学行为进行深入细致研究。

Extracting heat from hot dry rock (HDR) and nuclear waste disposal both need researches on granite mechanical characteristics at high temperature and high pressure in depth.
